That would be 2.5 pounds.
if i knew i would not have to ask
{| |- | 4 lbs. of white potatoes will make approximately 8 cups of cubed potatoes. On average, 1 lb. of white potatoes = 3 med. potatoes = 3 cups grated potatoes = 2 cups cubed potatoes = 1-3/4 cup mashed. |}
One pound of of white or russet potatoes makes approximately 1 3/4 cups of mashed potatoes. Using that measurement, then five pounds of potatoes would make approximately 8 3/4 cups of mashed potatoes. Source: http://southernfood.about.com/library/info/blequivp.htm
I would use 40 pounds.
well! you need 6 cups to make 3 servings
If mashed after cooking, approximately 8 cups.
Since 6 cups of water weighs 3 pounds, and potatoes are close to the same specific gravity as water, if you totally stuffed potatoes into the cups, they'd be about 3 pounds also. However if you're cubing them or shredding them etc. there's going to be some air there as well, so depending on what you're doing and how tightly packed I'd guess 2.5-3 pounds... Vaguely scientific answer ;)
That is approximately 2.2 cups of potatoes
If you mashed it, it would be 2 cups.
One pound of potatoes yields about three cups of peeled & sliced potatoes.
Are they having other vegetables. If so, then about 18 pounds of potato.
